Small Scale Caustic Soda Plant

Our company offers a wide variety of small scale caustic soda plant, if your output is low, you can choose a small caustic soda plant, if your output is high, you can choose a large caustic soda plant according to your needs. The production capacity of products reaches 2000~1,000,000 tons/year, which covers almost all the requirements of customers.

Abstract: The preparation of caustic soda by ion-exchange membrane method is one of the common preparation methods in the production of caustic soda.

Ion membrane electrolysis soda production is the most advanced process in the industrial production of caustic soda in the world: it has the advantages of low energy consumption, less pollution from three wastes, low cost and convenient operation and management. The by-product chlorine and hydrogen can be used to synthesize hydrochloric acid, or further process chlorine downstream products such as PVC, silicone and methane chloride. Caustic soda is widely used in papermaking, textiles, printing and dyeing, enamel, medicine, dyes, pesticides, tanning, petroleum refining, animal and vegetable oil processing, rubber, light industry and other industrial sectors, as well as in the extraction of alumina and the processing of metal products.

Main principle: Ion-exchange membrane caustic soda is made by electrolyzing salt water by ion-exchange membrane method to make caustic soda (ie sodium hydroxide). Pass through and prevent the passage of anions and gases, that is, only allow H, and 2+ to pass, while Cl,, OH, and bipolar products H and C1 cannot pass, thus preventing the anode product C12 and cathode 22 The product H2 is mixed and may cause The danger of explosion also plays a role in preventing C12 from reacting with another cathode product, NaOH, to generate NaClO, which affects the purity of caustic soda.

Production process: The main raw material of the chlor-alkali industry: saturated brine, but because the crude brine contains sediment, C&2+, Mg2+, Fe3+, S02- and other impurities, it is far from meeting the requirements of electrolysis, so it must be purified and refined.

About Asia

Asia is a scientific manufacturer of Small Scale Caustic Soda Plant dedicated to "zero emissions". The company works closely with many domestic universities and well-known industrial institutions. The company takes "zero discharge" of industrial waste water as its leading role.

Our company offers a wide range of Caustic Soda Plant, which covers nearly all requirements of the clients.If your production is low,you can choose small scale caustic soda plant, if you have high production, you can choose big scale caustic soda plant according to your requirements.

The process characteristics of ion membrane method for making caustic soda:

1. Characteristics of ion-exchange membrane lye evaporation

(1) The process is simple, the equipment is simplified, and the operation is easy. Since the ionic membrane lye contains only a very small amount of salt, in the whole process of evaporation and concentration, even if it produces 99% of the solid alkali, it is not necessary to remove the salt. This greatly simplifies the process equipment, that is, the necessary desalination equipment and process engineering for diaphragm alkali evaporation have been cancelled. Moreover, since there is no salt precipitation during the evaporation process, it is difficult to cause pipeline blockage. Water problems, make the operation easy.

(2) The concentration is high, the amount of evaporated water is small, and the steam consumption is low. The concentration of the ion-membrane lye is high, generally 30%, 33%, which is much higher than the 10%, 11% of the membrane lye, thus greatly reducing the steam used for concentration. Taking 32% lye as an example, if the concentration of the product is 50%, the amount of distilled water per ton of 50% finished caustic soda is: 1 000732%, 1000750%, 1125 kg.

If the diaphragm method electrolytic lye is also concentrated to 50%, the water volume of 6. ot will generally be distilled out. That is to say, concentrated to the same 50%, about 5.4t water is evaporated less than the diaphragm lye evaporation by the ionic membrane lye evaporation. Due to the reduction in the amount of evaporated water, the steam consumption is greatly reduced. Taking the double-effect process as an example, the steam consumption is generally only 0.73, 0.78t/t, and the steam space is also reduced accordingly, so that the equipment investment is also reduced accordingly.
